Polyurethane Boat Trailer Bow Roller Assembly – Fits Multiple Brands (Replaces 3"x5" with 1/2" Shaft)
This durable polyurethane bow roller assembly is engineered for various boat trailers, providing superior protection and smooth operation. The non-marking material safeguards your boat's hull from scuffs and scratches during loading and transport, while its robust construction ensures it won't rust or develop flat spots over time.
Designed as a direct replacement for JFATXTT 3" and 4" Bow Rollers, the MARKGOO 7x4 INCH Bow Stop, and the GlückMarine 5"x3" Bow Roller Assembly, this part simplifies maintenance and upgrades.
- Fits winch posts designed for a 3-inch inner roller width.
- Installed using the included 1/2" diameter shaft/bolt.
- Constructed from non-marking polyurethane that resists rust and flat-spotting.

Installation Guide
- Ensure the boat is securely positioned off the trailer's bow stop to relieve all pressure.
- Use a wrench to loosen and remove the nut from the existing bow roller bolt.
- Slide the old bolt out of the winch post bracket to release the old roller. Note the order of any existing hardware.
- Clean the bracket area of any dirt or debris before installing the new assembly.
- Position the new polyurethane roller between the winch post brackets.
- Slide the new 1/2" mounting bolt through the bracket, one end bell, the roller, the second end bell, and out the other side of the bracket.
- Securely fasten the nut onto the bolt.
- Do not overtighten—the roller must be able to spin freely with minimal resistance.
- Check for smooth rotation before loading the boat against the new roller.
Troubleshooting & FAQ
Q: How do I know if this roller will fit my trailer?
A: This assembly fits trailer winch posts that accommodate a 3-inch wide roller and use a 1/2-inch diameter mounting bolt. The total length with end bells is 5 inches. Please measure your existing setup to confirm compatibility.
Q: What is the difference between polyurethane and standard rubber rollers?
A: Polyurethane is a more durable, non-marking material that resists developing flat spots from prolonged pressure. Unlike black rubber, it will not leave scuffs or marks on your boat's hull.
Q: How tight should I fasten the mounting bolt?
A: The bolt should be tight enough to be secure, but not so tight that it prevents the roller from spinning freely. The roller needs to rotate smoothly as the boat moves against it.
Q: Will this roller mark or scuff my boat's hull?
A: No, this roller is made from a non-marking polyurethane/polyvinyl material specifically designed to protect your boat's finish.
Q: OEM vs. Aftermarket?
A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.
